This is completely my opinion! A well-made implementation and the impact is almost zero. After, if the guys are going to fuck in the middle of a Natura 2000 and that in addition the communities agree, it is dishonest on one side and the authorities who are not doing their job on the other. There will always be people to abuse or to let anything happen. But that's not the problem with wind power.

I don't know what Lumberjack means environmental problem but I think that, in terms of embodied energy, solar thermal is more profitable than wind turbines ...

I haven't entered into a sterile controversy over which style is the least worse but it was just a remark like that :)

I completely agree with Rooftop on the Thermal Chris. But good luck to get out of the current and balance it on the network with this type of device ...

Freudian slip?

Otherwise yes obviously it's not electricity but it "makes energy" anyway no?

For photovoltaics, the return on energy investment is allowed between 2 and 3 years.

Do you have an order of magnitude for wind power?

Heat is the most degraded form of energy, that's not what I was talking about.

I also agree with the thermal on you, Tof ... : Mrgreen:

In this case it is debatable ... but is the game (calculation) worth the candle?

As I just said: the question is not to know which one is the least worse ... I prefer to contribute to their development ... in any case it is nevertheless less worse than the fossils ...

uh isn't a zero missing there?
I was rather 20 years old according to simulations of 2 or 3 years ago ... what do you base yourself on as a model?
how many panels at what price, what type (mono, poly), insertion IN the roof, inverter batteries ... without labor, and WITH subsidies?

in fact is wind power subsidized? for the individual?

"Return on energy investment" = gray energy

therefore when the energy saved by the use of the panel compensates for the energy expended to manufacture and install the panels.

Regarding the time it takes for an individual to offset his expense with savings on his bill, it is indeed necessary to add a zero.
